Meaning

Thread incorporating metal, sometimes as a strip wound around a core. “Metal-thread” does not by itself identify solid gold, an alloy or a particular construction.

Spelling and pronunciation

  • Persian: نخ فلزی
  • Transliteration: nakh-e felezzi
  • English usage: Metal-thread

Spellings vary between dealers, museums and regions. Usage notes are under review.

A material category, not a precious-metal guarantee

Metal-thread describes thread incorporating metal. Some constructions use a metal strip around a core; others differ. The term alone does not establish alloy, core material, plating or solid gold. A catalogue’s exact medium statement is preferable to upgrading every reflective yarn to “gold thread.”

The Met’s barber’s apron is described as silk and metal-thread in a weft-faced compound plain weave. That identifies a woven textile, not a general metal embroidery technique. Woven pattern, added stitching and applied braid must remain separate processes even when all use metallic components.

Record shine, wear and construction separately

A photograph can show reflective areas and pattern placement, but lighting alters shine and colour. Darkened areas cannot automatically be diagnosed as corrosion. Nor can a bright surface certify precious-metal content. Detailed construction and material analysis belong to specialist examination or a technical catalogue.

Do not polish metallic yarns or test them with household chemicals. Threads, cores, surrounding fibres and joins may react differently. For contemporary handmade Iranian textiles, ask for a material statement and the maker’s technique; for historic work, keep conservation history and lawful provenance alongside the descriptive record.

Practical questions

Is all metal-thread zari?
Trade and historical terms vary. Preserve the source’s terminology and documented construction rather than treating names as interchangeable.
